About Blockbreaker

Blockbreaker is an implementation of the popular game Brickbreaker, which everyone had on their BlackBerry phones. I built Blockbreaker to enter a programming competition during my first year at the University of Portsmouth. I entered the competition as I had just discovered programming and wanted to see what I could do with it when I wasn't focussing on completing coursework. Blockbreaker became my first large Python program and was a success as I achieved first place in the competition, winning an Android tablet in the process.


This is an individual competition – group entries are not allowed. Use only Python and the graphics module. Don't write (object-oriented) classes and do not use non- standard libraries such as PyGame – any modules you use apart from John Zelle's '' must be part of the standard Python 3 distribution. However, if you want to add sound, I suggest using the winsound module (this only works on Windows, but you can assume that we will use a Windows computer to run your program). Do not re-write the game completely – it should still involve bat(s)/ball or an android eating apples (but of course, it could do other things as well!). Keep to the spirit of the unit and the competition, and make sure that your game would not offend anyone.

Technical Details

Blockbreaker is written in Python (2.7 but works with 3), it uses a single file with multiple functions and predominately uses Lists to keep track of game items such as the blocks and score as every block has a different value. Every second the game calculates whether the ball has hit a block, wall or the bat and determines whether it needs to alter the projectory of the ball. When a certain amount of blocks are hit the game levels up which increases the ball speed and changes the colour of the blocks. For creating the Graphics it uses John Zelle's '' which was used heavily in University coursework. It also uses built in modules to read/write the highscores file, control the speed of the ball and randomise the direction of the ball when it hits a surface. The source code is available on Github.
